Email: [email protected] Abstract Rhinosporidiosis is a chronic granulomatous inflammation caused by Rhinosporidium seeberi which is endemic in India but also reported in other parts of the world. A study was done at Department of Pathology, Government Thiruvarur Medical College, Thiruvarur district from Jan 2015 to Dec 2015. The case study included 65 cases of nasal mass.of these 65 cases, 25 cases were reported as rhinosp oridiosis by HandE stained section. Special stains like GMS and PAS were done.

ABSTRACT Keywords: Fungus; Fungal infections due to pathogenic or opportunistic fungi may be superficial, cutaneous, subcutaneous Mycosis; and systemic. With the upsurge of at risk population systemic fungal infections are increasingly common. Opportunistic; Diagnosis of fungal infections may include several modalities including histopathology of affected tissue Systemic which reveal the morphology of fungi and tissue reaction. Fungi can be in yeast and / or hyphae forms and tissue reactions may range from minimal to acute or chronic granulomatous inflammation. Different fungi should be differentiated from each other as well as bacteria on the basis of morphology and also clinical correlation. Special stains like GMS and PAS are helpful to identify fungi in tissue sections.

Subsequently, a new group of microorganisms at the boundary between an- imals and fungi was reported. Several microbes with similar phylogenetic backgrounds were soon added to the group. Interestingly, these microbes had been considered to be fungi or protists. This novel phylogenetic group has been referred to as the DRIP clade (an acronym of the original members: Dermocystidium, rosette agent, Ichthyophonus, and Psorospermium), as the class Ichthyosporea, and more recently as the class Mesomycetozoea. Two orders have been described in the mesomycetozoeans: the Der- mocystida and the Ichthyophonida. So far, all members in the order Dermocystida have been pathogens either of fish (Dermocystidium spp.

  • Rhinosporidium Seeberi: a Human Pathogen from a Novel Group of Aquatic Protistan Parasites
    Research Rhinosporidium seeberi: A Human Pathogen from a Novel Group of Aquatic Protistan Parasites David N. Fredricks,*† Jennifer A. Jolley,* Paul W. Lepp,* Jon C. Kosek,† and David A. Relman*† *Stanford University, Stanford, California, USA; and †Veterans Affairs, Palo Alto Health Care System, Palo Alto, California, USA Rhinosporidium seeberi, a microorganism that can infect the mucosal surfaces of humans and animals, has been classified as a fungus on the basis of morphologic and histochemical characteristics. Using consensus polymerase chain reaction (PCR), we amplified a portion of the R. seeberi 18S rRNA gene directly from infected tissue. Analysis of the aligned sequence and inference of phylogenetic relationships showed that R. seeberi is a protist from a novel clade of parasites that infect fish and amphibians. Fluorescence in situ hybridization and R. seeberi-specific PCR showed that this unique 18S rRNA sequence is also present in other tissues infected with R. seeberi. Our data support the R. seeberi phylogeny recently suggested by another group. R. seeberi is not a classic fungus, but rather the first known human pathogen from the DRIPs clade, a novel clade of aquatic protistan parasites (Ichthyosporea). Rhinosporidiosis manifests as slow-growing, that has been difficult to classify. Recently, tumorlike masses, usually of the nasal mucosa or R. seeberi has been considered a fungus, but it was ocular conjunctivae of humans and animals. originally thought to be a protozoan parasite (2). Patients with nasal involvement often have Its morphologic characteristics resemble those of unilateral nasal obstruction or bleeding due to Coccidioides immitis: both organisms have polyp formation. The diagnosis is established by mature stages that consist of large, thick-walled, observing the characteristic appearance of the organism in tissue biopsies (Figure 1).

A histopathological examination is mandatory for definite diagnosis which helps in recognition of the fungus and early treatment of the infection avoiding dissemination and fatality in untreated infections Aims: To study the clinicopathological spectrum of deep fungal infections Methods: A total of 22 cases were studied in detail with a confirmed histopathologcal diagnosis of deep fungal infection. All the biopsies were fixed in 10% formalin and sent for histopathological examination. The biopsies were stained with hematoxylin and eosin (H and E). Special stains including periodic acid Schiff (PAS), and Grocott's methenamine silver (GMS) were done for identification of fungus. The histopathological and cytological features were noted. Results: Among these cases, 18/22 (%) cases had clinical suspicion of fungal infection. The clinical symptoms varied from ABSTRACT nodules, ulcerative plaque, pustule, to sinus tract formation. The dermis showed varied tissue reactions which included necrotizing inflammation, neutrophillic infiltrate, giant cell reaction, granulomas and lymphoplasmacytic infiltrate.

  • Laboratory Manual for Diagnosis of Fungal Opportunistic Infections in HIV/AIDS Patients
    The human immunodeficiency virus per se does not kill the infected individuals. Instead, it weakens the body's ability to fight disease. Infections which are rarely seen in those with normal immune systems can be deadly to those with HIV. People with HIV can get many infections (known as opportunistic infections, or OIs). Many of these illnesses are very serious and require treatment. Some can be prevented. Of the several OIs that cause morbidity and mortality in HIV infected individuals those belonging to various genera of fungi have assumed great importance in recent past. Since these OIs were earlier considered as nonpathogenic, the diagnostic services for confirmation of their causative role need to be strengthened. This document is an endeavour in this direction and hopefully shall be useful in establishing early diagnosis of fungal OIs in HIV infected people thus assuring rapid institution of specific treatment.

Tres o quatre assignatures de micro a la carrera, i cap d'elles tractava a fons amb protistes i menys els parents unicel·lulars dels animals.

Així que em vaig presentar al despatx del Iñaki vestit amb el tratge de comercial de Tecnocasa, per veure si podia fer les pràctiques del Màster amb ells. El primer que vaig volguer remarcar durant l'entrevista és que no pretenia anar amb tratge a la feina, que no es pensés que jo de normal vaig tan seriós...

Per tant, aquí el meu primer agraïment i molt gran, al Iñaki, per permetre'm, no només fer el màster, sinó també permetre'm fer aquesta tesis al seu laboratori.

Although their invasive cells in the tissues of infected To resolve this taxonomic standoff, a team of humans and other animals are abundant and readily detec- scientists from Sri Lanka, where R. seeberi infections are table histologically, they have been intractable to isolation common, and Brazil, where lobomycosis is endemic, and and culture. Thus, it has not been possible to objectively the USA was assembled to study R. seeberi’s and place them in any of the kingdoms in which all living enti- L. loboi’s phylogenetic links with other eukaryotic orga- ties are classified. In addition to their uncultivatable sta- nisms. The strategy was to collect fresh tissue samples tus, L. loboi and R. seeberi shared in common from cases of lobomycosis and rhinosporidiosis, isolate morphological features that resemble those of certain pat- genomic DNAs and then amplify their 18S small subunit hogenic fungi and protozoans: viz. essentially similar (SSU) rDNA by using standard primers and PCR techno- inflammatory host reactions, unresponsiveness to antifun- logy.
